Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination with a track-plate, of an encircling belt composed offlexible material, and antifriction devices loosely carried by saidbelt, substantially as described.

2. The combination with a track-plate, of an encircling belt composedot' flexible material and being provided with spaces, and antifrictiondevices arranged in said spaces, substantially as described.

3. The combination with a track-plate, of an encircling belt composed offlexible material and being provided with spaces, and antifriction.devices riding on said plate and protruding through said spaces,substantially as described.

4. The combination with a track-plate, of an encircling belt havingtapering openings, bushings in said openings, and antifriction devicesin said bushings, substantially as described.

5. The combination with a track-plate, of a belt encircling the same,bushings in said belt, and antifriction devices riding on saidtrack-plate and protruding through said bushings, substantially asdescribed.

6. The combination with a track-plate, of an encircling belt, taperingbushings in said belt, and antifriction-rollersin said bushings,substantially as described.

7. The combination with a track-plate, of an encircling belt, bushingsin said belt, and an tifriction-rollers of ditterent lengths in saidbushings, substantially as described.

S. The combination with a track-plate, of an encircling belt, bushingsin said belt, and

antifriction-rollers of dierent lengths in said bushings, said rollersbeing arranged in alternating series, substantially as described.

9. The combination with a track-plate, of an encircling belt, bushingsin said belt, the openings in said bushings being contracted at theirouter ends, and antifriction-rollers in said bushings and projectingthrough said contracted openings, said rollers being staggered withrelation to each other, substantially as described.

l0. The combination Witha track-plate, of an encircling belt, bushingsin said belt, antifriction devices in said bushings, and means forpreventing the displacement of said antifriction devices in saidbushings, substantially as described.

l1. The combination with a track-plate, of an encircling belt, bushingsin said belt, antifriction-rollers in said bushings, and projections onsaid bushings for preventing the displacement of said rollers therefrom,substantially as described.

l2. The combination with a track-plate, of an encircling belt, bushingsin said belt, antifriction-rollers in said bushings, said rollers beingstaggered with relation to each other, and projections on said bushingsfor preventing the displacement of said rollers, substantially asdescribed.

13. The combination with a track-plate, of an encircling belt, bushingsin said belt, antifriction-rollers in said bushings, said rollers beingof different lengths and arranged in alternating series, and projectionson said bushings for preventing the displacement of said rollers,substantially as described.

In testimony whereof I hereunto aftix my signature, in the presence oftwo witnesses, this 17th day of May, 1902.
